Question

I have a database full of names like:

John Smith  
Scott J. Holmes  
Dr. Kaplan  
Ray's Dog  
Levi's  
Adrian O'Brien  
Perry Sean Smyre  
Carie Burchfield-Thompson  
Björn Árnason

There are a few foreign names with accents in them that need to be converted to strings with non-accented characters.

I’d like to convert the full names (after stripping characters like ” ‘ ” , “-“) to user logins like:

john.smith  
scott.j.holmes  
dr.kaplan  
rays.dog  
levis
adrian.obrien  
perry.sean.smyre
carie.burchfieldthompson  
bjorn.arnason

So far I have:

Fullname.strip()  # get rid of leading/trailing white space
Fullname.lower() # make everything lower case


... # after bad chars converted/removed
Fullname.replace(' ', '.') # replace spaces with periods

Take a look at this link [redacted]

Here is the code from the page

def latin1_to_ascii (unicrap):
    """This replaces UNICODE Latin-1 characters with
    something equivalent in 7-bit ASCII. All characters in the standard
    7-bit ASCII range are preserved. In the 8th bit range all the Latin-1
    accented letters are stripped of their accents. Most symbol characters
    are converted to something meaningful. Anything not converted is deleted.
